Circuit~ The complete path or part of the path of an electric current.
Charge~ The electrical property of electrons and protons that produces attraction and repulsion between them.
Conductor~ a material in which a electric current can flow freely.
Current~ the flow of electrons.
Direct current~ a current where the flow of electrons never changes direction.
Distribution system~ The poles, wires, cables, substations etc required to transport electricity energy to people's homes.
Efficiency~ the amount of a utility's power generation process that is used to produce power.
Electron~ The basic particle that orbits the nucleus of an atom.
